Ginkgo Letter: Reunion and Confession in Five Years

Please Recommend Some Good Books, but They Are in Short Supply. No Systematic Writing.

There is a shortage of books, please recommend some books. Don't be systematic, I'm really tired of seeing it. If it's a farming article, it's best not to make paper and gunpowder to provide relief for work. The routines are the same and they look like they were made from the same mold.
